To all whom it may concern:

Be it known that T, GRAVES GRIFFITH, a citizen of the United States,residing in the city and county of San Francisco and State ofCalifornia, have invented certain new and useful mission-Case Trusses,of which the following is a specification.

The present invention relates to trusses for supporting and bracing theoverhang of transmission-cases in certain makes of automobiles.

A principal object of the invention is the provision of means for theprevention of vibration in the crank and transmission cases ofautomobiles, thereby providing against the getting out of alignment ofthe driving mechanism and the consequent wear of these parts andattendant loss of power.

A further object sought in a stabilizer of the,character described is toprovide a device that, in addition to being efficient, will be of cheapand simple construction, and easily and readily installed and adjusted.

Tn the accompanying drawings, forming a part of this specification and'in which like parts, throughout, are designated by similar referencecharacters, Figure 1 illustrates a view, in perspective, of anautomobile frame and transmission-case, with the device shown installed;Figure 2 is a view in transverse section, showing manner of attachmentto automobile frame andtransmission-case; Figure 3 is a plan view of theadjustable connection uniting the two body-members of the device, andthe means whereby adjustment of these members is secured relative toeach other and to the automobile frame and transmissioncase.

. Referring more particularly to the drawings, 1 deslgnates anautomobile frame, 2 the transmimion-case, 3 the flanges of thetransmission-case, 1 the two similar trussmembers, 5 the curved sectionsof the trussmembers conforming to the contour of the conic surface ofthe transmissioncase, 6 and 7 extremities of the truss-members 4, shapedto embrace, respectively, the flanges 3 of the transmission-case 2 andthe automobile Improvements in Automobile Transframe 1, and 8 the meansadjustably connect- 5o ing the truss-members 4.

e truss is comprised of two similar members 4, having, respectively,curved sections 5 conforming to sections of the conical surface of thetransmission-case 2, extremities 6 and 7 formed to embrace,respectively, the flanges 3 of the transmission-case 2 and the Yautomobile frame 1, and an adjustable connecting means 8 for uniting thetwo members 4C, comprised of two eye-bolts 9, with bodies bentrightangularly, the threaded end of the one entering the eye of theother and fitted with nuts for securing them in position and efiectingadjustments.

Having thus'described the character and 65.-

purpose of my invention, I claim, and desire to secure by LettersPatent:

1. The combination, in a device of the character described, of anautomobile frame and a transmission-case, truss members extending fromopposite sides of said transmission-case to the adjacent side member ofsaid automobile frame, said truss members having each an extremityshaped to partly embrace and be suported by said side member of saidframe and an extremity each so shaped as to embrace opposite flanges ofsaid transmission-case, and means, as set forth, for connecting saidtruss members and adjustably regulating the tension therebetween,whereby movement, in any direction, of said transmission-case isprevented.

2. In combination, in a device of the character described, an automobileframe and a transmission-case, truss members extending respectively fromopposite flanges of a transmission-case to the adjacent sides of anautomobile frame, thesaid truss members having each an extremity shapedto embrace respectively opposite flanges and portions of a sotransmission-case and an extremity each shaped respectively to passbeneath an adjacent side of said frame and upwardly therealong and hookover the top thereof, and means, as set forth, for connecting'said trussmembers and adjustably regulating the tension therebetween.

3. The combination, in a device of the character described, of anautomobile frame ranged to engage as an adjustable unit in and 'atransmisslon-case, truss-members reconnecting the said trussmembers, and10 spectively suspended from and supported by means carried by the saidcoupling means opposite sections of said automobile frame for tensionadjustment relative to the indiandextending therefrom to and engagingvidual members of said pair and the said and supportmg saldtransmlssion-case, couautomobile frame and said transmission-case. plingmeans comprising a pair of eye-bolts having angularly formed bodies andar- GRAVES GRIFFITH.
